THOMAS M. MORTON, OF BALTIMORE, MARYLAND.

STEAM-RADIATO R.

SPECIFICATION forming part of Letters Patent No. 233,428, dated October 19, 1880.

Application filed August 27, 1880. (No model.)

To all whom it may concern:

Be it known that I, THOMAS M. MORTON, of Baltimore city, State of Maryland, have invented certain new and useful Improvements in Steam-Radiators and I hereby declare the same to be fully, clearly, and exactly described as follows, reference being had to the accompanying drawings, in which Figure 1 is a sectional view of the device; Fig. 2, a plan of the interior side of the base of the steam-chamber; Fig. 3, a perspective view of the earthenware slab; and Fig. 4. a sectional view, on an enlarged scale, of the walls of the hot-air chamber.

My invention has reference to radiators to be used in connection with steam-heating systems for apartments or buildings; and it consists in a radiator constructed as hereinafter described, and combined with a jacketed hotair chamber provided with pipes for conduct ing the heated air to other apartments.

In the accompanying drawings, A is the airchamber, having outlet-pipe D and an inletpipe, D, and A is the radiator-front, which may be, and preferably is, corrugated.

The chamber A is jacketed by means of a lining, 71/, next to its inner walls, of a mixture of about equal parts of steatite and calcined gypsum mixed with sufficient water to cause the compound to set. Next to'this is a lining, h, of sheet metal, (lead or zinc being preferred,) and upon it is laid another coat or layer, h, of the steatite and gypsum, which is finally protected by a second sheet-metal (zinc or lead) lining, h.

The radiator or steam-chamber proper, A, consists of two parts-a base-piece, B, having longitudinal ribs 0, of a height equal to that ofits peripheral flange, and transverse shallow ribs 0, thereby forming a channel or chamher, 0?, all around. Within the central space fits closely against the flanges c c an earthenware block or slab, Gr, longitudinally perforated, as shown at g.

B is the steam-inlet pipe O, the outlet E, the drip, and F the gage.

Bolts or screws a I) serve, respectively, to

secure the parts A and B together and to hold them in place within the chamber A.

In operation, steam being conducted through the chamber A B, it is thereby heated as well as the earthenware slab, the steam findl in g passage through the perforations g.

The front plate, A, acts as a radiator to heat the apartment in which the heater is placed, while the rear plate, B, serves to heat the air in the jacketed chamber A. From the latter the heated air is led through the pipe or pipes D to other parts of the building.

The earthenware slab G serves to retain the heat after the steam is out off and prevent sudden changes of temperature, which are liable to loosen the packing or joints between the plates.

Thejacketing of the chamber A, consisting in a series of layers of a non-conducting material separated by plates, as described. forms an almost perfect barrier to heat-an end which is furthermore conduced to by the peculiar nature of the packing of steatite and gypsum.

What I claim is 1. In combination with the steam-chamber A B, constituting one of the external walls of the device, the air-chamber A contiguous thereto and provided with pipes, as set forth.

2. In combination with the steamchamber, consisting of easing B and cover-plate A, the air-chamber A, having a non-conducting lining, substantially as set forth.

3. The steam-chamber A B, having a longitudinally-perforated slab, G, as set forth.

4. The air-chamber A, having a non-conducting lining of steatite and gypsum, as set forth.

5. In combination with the steamchamber A B, having the perforated earthenware slab G, the air-chamber A, having a non-conducting lining of steatite and gypsum, and suitable service-pipes, as set forth.

THOMAS M. MORTON.
